示例1: calculateCurrent
void FadeChannel_Test::calculateCurrent()
{
FadeChannel fch;
fch.setStart(0);
fch.setTarget(255);
// Simple: 255 ticks to fade from 0 to 255
for (uint time = 0; time < 255; time++)
QCOMPARE(fch.calculateCurrent(255, time), uchar(time));
// Same thing, but the value should stay at 255 same after 255 ticks
for (uint time = 0; time <= 512; time++)
QCOMPARE(fch.calculateCurrent(255, time), uchar(MIN(time, 255)));
// Simple reverse: 255 ticks to fade from 255 to 0
fch.setStart(255);
fch.setTarget(0);
for (uint time = 0; time <= 255; time++)
QCOMPARE(fch.calculateCurrent(255, time), uchar(255 - time));
// A bit more complex involving decimals that don't produce round integers
fch.setStart(13);
fch.setTarget(147);
